KSS 27

The KSS 27s - S standing for simple, simple to build using KSS the Kelsall Swiftsure Sandwich method by the owner or boat builder.

There is nothing small about the KC27. She has the space of a big boat, with two very good double berths, and everything else you could want while sailing. A good performer, she has won lots of races. She tacks without hesitation and is well balanced. The owner can leave the helm for long periods of time. The extra length of the 27 makes if a very practical cruiser.
